TSK Manager v0.9.8

[calvinpark]

This is a major overhaul.

1. Tried to make it less daunting to a newcomer.
   a. Covered only the happy path in the main section.
   b. Non-essential information was moved into the Troubleshooting fold.
   c. Removed the Fingerprinting & SSH sections
2. Uses the new TSK Manager
3. Downloaded the build cache so that in-car steps take less than 5 minutes.

I've considered adding the expected time for each section, but they now all take only around 2 minutes.

Now waiting for

1. openpilot v0.9.8 release commaai/openpilot#34737 to merge so that commaai/devel has the v0.9.8 release.
2. Update the installer to use the commaai/devel branch.
3. Rebase tskm-0.9.8 onto commaai/devel
4. Push tskm-0.9.8 to optskug/openpilot.

@nelsonjchen @chrispypatt Still waiting for the official release, but the doc is ready to be reviewed. The Setup Guide is completely new so just read it using the preview. The Forks section changes are better seen through the diff. Thank you

[chrispypatt]

Very nice rewrite of the doc! Nice work. I'm a fan of the troubleshooting expandable sections.

@nelsonjchen Ready to merge in case you want to check it out

[nelsonjchen]

Looks fine to me. It's git, nothing is lost. That said, I think we had some offers for people to review a bit in Discord but maybe we can just ask them to review the merged product.
